Foam Insulation

Why is Spray Foam better than fiberglass blow in or batt insulation in my attic?

Fiberglass (blow in or batt) insulation allows hot attic air to leak into your house through the ceiling. This is called convection. Spray Foam insulation is sprayed onto the inside of the roof plywood and tightly seals the attic. This prevents the hot air from entering or building in the attic space. It also prevents the hot air from leaking in through the ceiling or around lights in the ceiling. In addition, the A/C ductwork is not exposed to hot attic air and condensation problems.

How does Spray Foam affect my air condition unit?

With Spray Foam insulation, A/C ductwork (typical duct R-value = 6) is not exposed to hot attic air and condensation. Also, the house is tightly sealed, which prevents air infiltration (air can blow through typical fiberglass insulation).  The size of A/C units or even the number in larger homes can be reduced significantly. What is saved in reducing the size or number of A/C units can pay for the cost of Spray Foam insulation.

Do I need to vent my attic?

No. When utilizing Spray Foam insulation, attics are designed without venting.  On existing homes, attic vents are sealed. Traditional attic and crawlspace venting allows hot, humid outside air to saturate the attic and insulation, which provides ideal conditions for mold & mildew growth. Unvented Spray Foam attics keep hot, humid air outside, sealing the building envelope. This is not traditional, but most architects and builders see the advantages, and building codes have changed to eliminate venting when using Spray Foam insulation.

Does it cost more?

Spray Foam costs less in the long run, but does cost a little more up front. Energy savings and smaller A/C units will pay for the additional cost of Spray Foam insulation

How does Spray Foam protect against humidity?

During the summer months, the likelihood of mold growth is very high due to the increase in humidity.  Spray Foam prevents moisture infiltration and air leakage and allows the A/C unit(s) to keep the inside moisture level low without the A/C running as often.

Can Spray Foam only be used in new construction?

NO. Spray Foam can be installed in the attic of a new or existing home, or in the walls during a remodel.

Why haven't I heard of this before?

Spray Foam has been used since the 1950's and has improved to comply with all emissions regulations and building codes. Consumers are becoming more and more aware of the tremendous benefits.
